10kVA-500kVA single phase transformer supplier from china-Guanghui

Oil-Immersed Transformers

Single-Phase Transformer (10kVA - 500kVA)

Single-Phase Transformer (10kVA - 500kVA)

Our single-phase transformers are designed for standard step-down and step-up voltage conversions. Available in both dry-type and oil-immersed configurations, they are widely applicable for industrial and civil isolation and decentralized power distribution scenarios.

Core Parameters:

• Phase / Frequency: Single-phase / 50Hz

• Capacity Range: 10kVA - 500kVA

• Vector Group: I/I0

icon Product Features

Versatile Configurations

Available in dry-type (Class F insulation) or oil-immersed (Class A insulation) to suit indoor and outdoor environments.

Stable Regulation

Features off-circuit tap changing (±5%) for reliable and straightforward voltage adjustment across civil grids.

Thermal Efficiency

Strict temperature rise limits (Winding ≤100K, Core ≤80K) guarantee safe continuous operation under load.

Compact Footprint

Single-phase design minimizes physical space requirements, ideal for isolated civil or decentralized industrial setups.
